1. Most commonly a reference to "rest and relaxation", a rather self-explanatory concept.

2. Also a reference to "Rum and Ritalin." The simultaneous consumption of both alcohol (generally rum) and small amounts of Ritalin (or other similar medications). The desired effect is generally to attain the condition of feeling physically drunk due to the alcohol, yet still maintaining a somewhat focused, sober mindset thanks to the Ritalin counter-acting the alcohol. A somewhat cheaper alternative to using mind-altering drugs, as it lowers inhibitions while also allowing a certain degree of "control" to the consuming parties. (Though it can be potentially quite dangerous) The term was slightly popularized after being used on the television show "30 Rock" in a passing reference.

3. A reference to "Redbull and Ritalin." Consuming both Redbull (or other similar energy drinks) and Ritalin (or other similar medications) in order to keep oneself awake and focused. Popular among over-worked college students who need to cram for tests by pulling all-night study sessions.

1. Brie needed some r&r after having to pull a 70-hour work-week at the hospital.

2. Toby decided to have some r&r because he wanted to get f**ked-up without losing total control of his mind.

3. Steve needed some r&r so he could get ready for the big Biology test tomorrow.
